. (JOIN-COIWLIRLOLLE1) LOOK MECHANISM;

To all whom it may concern:

Be it known that I, RALEIGH B. BUZZAIRD, acitizen of the United States, and a resident of WVashington, in the District of Columbia, have invented a new and useful Improvement in Coin-Controlled Lock Mechanism,

of which the following is a specification.

This invention is an improvement in coinlocking .means for parcel-checking lockers. The doors of such lockers are locked by the users through the deposit of acoin, which also enables the owner of the checked property to remove the key from the lock, to constitute his check. By use of the key he can unlock the locker again and take out his belongings, the key then being locked in the lock against theft or loss. f

The object of the invention is to prevent patrons losing their service by operating the look after deposit of a coin while the door is standing open. In such event, of course, the bolt would be projected, but the door would not be locked, and as the coin would have passed beyond'its operative position, the patron would be obliged to retract the bolt, put in another coin and operate the lock again. In an application filed of even date herewith I disclose andclaima construction in which a. li 'on the door closes the entrance to the coinrop'when the door is closed, so that'inconsequence' the coins must be fed to the look when thedoor is open, which makes it possible for thoughtless persons to project the bolt when the keeper on the door is not present to receive it. In that application I also disclose and claim a coin-arresteiywhich normally obstructs the path of the .coin to the coin-mechanism of the lock and which renders any'attempt tooperate the lock idle, until the door is closed, at which time the lip acts'upon the arrest'er to remove it from the coin. It is also incidentally shown in that case that the auxiliary part of the lock which constitutes the arrester has a portion which normally blocks 'or restrains operation ofthe lock mechanism proper, more especially b coiiperating with a detent which holds the bolt against movement from unlocking to locking position and which is displaced through the instrumentality of the coin.

The present invention comprises, specifically, such means for blocking the operation of the lock mechanism, and in its broad aspect is generic' to' auxiliary means for pre- Specification of LettersPatenti Patent d O t 11 1921 Application filed July 17,

venting operation, of the coin lock after deposit of the coin and while the door subject to the lock is open. Claims are also included herein to the combination of both forms of means, serving as a double-check to prevent patrons losing their coins, and also to comhlnations including door-operated meansfor closing the coin-entrance.

In the accompanying drawings, forming part hereof:

Figure l is a front elevation of a locker and lock, showing how the door-lip closes the coin-entrance and cooperates with the auxiliary means of thelock;

Fig. '2 is a front elevation of the lock on a larger scale;

Fig. 3 is a rear elevation of the lock in the unlocked condition, with the cover ofthe coin-disk casing partly broken away, show- The front plate or escutcheon 1 has a knob 2, a coin-entrance 3 and the key-slot endof a key-cylinder 4 on itsouter side. This keycylinder and its cylinder casing 5 constitute a well-known form of lockunit, containing tumbler arrangements whereby the key can be removed inthe locking condition only, and is locked in'the look by the tumblers when the lock'is open. These matters beingv familiar require no illustration.

A swinging bolt 8 ispivoted at 11, and is projected bya spring 17. The bit 14 of the key-cylinder coijperates with a recess or socket 15 in the rear portion of the bolt. A bell-crank detent 18 is pivoted at 19 and its rearwardly extending armis formed with a primary holding shoulder 21, which cohperates with aprojection 23' on the bolt tohold the latter in its fully retractedcondition, the detent having "a spring 24 whereby it engages automatically. 7 j

The contact extremity of the downwardly being connected with the boltisalso moved to the p'osition in 'which the key can be removed by the cuser,to'constitute his, check. hen he wishes to regain his property he inserts the keyand turns (it in the unlocking direction, thereby retractingthe bolt, which caught and held bythe detent, the key being thereby locked in the cylinder until the next checkingoperation.

As in my other application aforesaid, a

lip -46 is fixed to the use edge of the door 47, ofsiich proportions and arrangement as to cover completely and closely the coin-entrance 3 in theffront plate 1 of the lock, and overlap; adjoining portions oftheplate, With this lip in closed position, it is impossible to introduce, a coin or any other object into the coin passage and thenceinto the in terior of the. lock; .Thus, an inattentive person c'annotlosea com in the lock of a locker which is in usernor can the service of the locker be obtained without cost by placingarticles in. it, closing the door and then displacing thdetentlS by a wire inserted through the coin-drop. Theauxiliary means of this invention, as embodied in the particular construction illustrated, comprises a membertS in the interior of thelock, 'whichlpossesses a portion 5 1 adapted .to engage or block the detent 18, so as to prevent premature operation thereof to release the bolt 8.] This member is actuated through an opening 52 in the front plateby the lip 46, preferably through the intermediary of a finger 51 on the memberft8 projecting outward through the opening, in

positionto be struck and repressed by the lip whenthe door is closed. V

The form and arrangement of the mem her, or part 48*a'nd its specific mode of cooperation with the coin-lock mechanism may be varied Preferably it is in the form of r-awsubstantially horizontal piece in the lock, transverse to the coin-drop and the depending arm 26 of the detent, which are substantially parallel and opposite each other, and acting upon both. One end of the member be pivoted upon a lug 5O bent flout ofthe inner wall of the coin-drop. Theother end is hooked, shouldered or provided'with a projection orrecess, to form the portionet, Which is normally disposed in front of the arm of the detent to prevent the same moving sufliciently under the action of the knob and coin to release the bolt. An intermediate portion 419 is formed as a shoulder or projection which normally intercepts the path of the coin suiliciently to prevent it from reaching 'the'c'oin-dislr. A spring 53 normally holds the member i8 in its d'etent-blocking and coin-arresting position, and returns it automatically to such position afterbeing displaced by the action of the door-lip. I i

It will, therefore, be understood that after a coin has been put in the lock, with the door open, and even if the coin could rcachthe coin-disk, it willbe impossible to project the bolt by turning the knob, because. the detent is positively held. The coinjar; rester, when present, however, prevents the coin entering the pocket of the disk. 7

Various other embodiments and applications of the invention will suggest them-. selves to those skilledin the art. I do not necessarily limit myself to the detent' 18 as the part of the coin-lock mechanism proper with which the blocking devicecoeperates. What I claimgas new is: r j V H 1.
